A nonagon is a closed shape that has nine sides. If it is a regular nonagon, all nine sides are the same length, and all the angles are equal.Know More
The sum of the interior angles of a nonagon is 1260 degrees. If it is a regular nonagon, then all nine angles have the same measurement of 140 degrees.
The term "nonagon" was coined during the 17th century from a combination of words. It begins with the Latin word "nonus," which means "nine." The last part of the word "gon" is patterned after Latin and Greek words meaning "angle. " Literally translated, "nonagon" means "nine angles."Learn More

A nonagon, or enneagon, is a polygon with nine sides and nine vertices, and it has 27 distinct diagonals. The formula for determining the number of diagonals of an n-sided polygon is n(n - 3)/2; thus, a nonagon has 9(9 - 3)/2 = 9(6)/2 = 54/2 = 27 diagonals.Full Answer >
